Technical Field

[0001] This invention relates to the field of puncture positioning technology, specifically a puncture positioning device for percutaneous endoscopic discectomy. Background Technology

[0002] Percutaneous endoscopic discectomy (PED) is a minimally invasive spinal surgery. Specialized instruments are used to insert an endoscope to the lesion site, and then the herniated disc tissue or bone compressing the nerve is removed, relieving nerve compression and reducing pain. During the puncture process, X-rays are typically used to confirm the lesion location and determine the puncture position and angle. However, the surgeon usually needs to maintain the needle angle while slowly advancing the needle and manually fixing it for extended periods. Prolonged hand-held manipulation can lead to hand fatigue and potential deviation, and the surgeon's workload is relatively heavy. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-11In this embodiment of the invention, a percutaneous endoscopic discectomy puncture positioning device includes a placement module 100. The placement module 100 includes an operating table 110 and several mounting rails 120. Several connecting frames 121 are provided on the mounting rails 120. An abutment plate 122 is slidably connected inside the connecting frame 121. A positioning screw 123 is screwed onto the connecting frame 121 and rotatably connected to the abutment plate 122. Several limiting frames 150 are slidably provided on the mounting rails 120. Insertion blocks 152 are slidably connected to the limiting frames 150. Positioning screws 151 are screwed onto the limiting frames 150. The positioning screws 151 pass through the insertion blocks 152, and the end of the positioning screws 151 abuts against the mounting rails 120, which can limit the movement of the puncture. The position of the limiting frame 150 is controlled, and the plug-in block 152 can be restricted on the limiting frame 150 by the positioning screw 151. Several support mechanisms 140 are provided at the bottom of the operating table 110. The operating table 110 is provided with a limiting mechanism 130, which is used to support the arm. The bottom of the operating table 110 is provided with a positioning mechanism 160, which includes a positioning frame 161 and a magnetic piece 164. The positioning frame 161 is fixedly connected to the operating table 110, and the magnetic piece 164 is fixedly connected to the positioning frame 161. The bottom of the support mechanism 140 is provided on the adjacent limiting frame 150. The limiting frame 150 can support the operating table 110 through the support mechanism 140. A guide module 200 is provided on one side of the operating table 110. The guide module 200 includes several fixed seats 210, several U-shaped rods 220, and a sliding frame 230. The sliding frame 230 is set on several U-shaped rods 220. Two U-shaped rods 220 can support the sliding frame 230. The two ends of the U-shaped rods 220 pass through the interior of two fixed seats 210 respectively. The sliding frame 230 is fixedly connected to a T-shaped plate 240. The operating table 110 has a U-shaped groove corresponding to the T-shaped plate 240. The T-shaped plate 240 is rotatably connected to a limit ball 241. The limit ball 241 is fixedly connected to a guide tube 250. The limit ball 241 has a round hole corresponding to the guide tube 250.

[0020] Specifically, the mounting rail 120 can be set on the edge of the bed, and the connecting frame 121 can be inserted into the edge of the bed. Then, the positioning screw 123 can be rotated, and the positioning screw 123 can drive the abutment plate 122 to move upward, so that the abutment plate 122 abuts against the edge of the bed, thereby fixing the mounting rail 120 on the edge of the bed. Then, the limiting frame 150 can be inserted into the adjacent mounting rail 120. At this time, the mounting rail 120 can support the operating table 110 through the limiting frame 150 and the support mechanism 140. The positioning screw 151 can be rotated, so that the positioning screw 151 abuts against the mounting rail 120, positioning the limiting frame 150, thereby limiting the position of the operating table 110. The T-shaped plate 240 can be abutted against the top of the operating table 110, so that the guide tube 250 passes through the U-shaped groove of the operating table 110. The position of the T-shaped plate 240 on the operating table 110 can be adjusted according to the puncture location and angle, so that the sliding frame 230 can be moved horizontally along the two U-shaped rods 220. The magnetic piece 164 can attract the T-shaped plate 240, so that the T-shaped plate 240 is attached to the operating table 110. This can minimize the random movement of the T-shaped plate 240 on the operating table 110 and play a certain limiting role for the T-shaped plate 240. After the adjustment is completed, the puncture tool can be passed through the limiting ball 241 and the guide tube 250. The puncture tool is guided to puncture through the limiting ball 241 and the guide tube 250. The T-shaped plate 240 and the guide tube 250 can play a certain auxiliary fixing role for the puncture tool, which helps to reduce the doctor's operating burden, reduce hand fatigue, and facilitate the smooth performance of the puncture operation.

[0021] Example 1

[0022] like Figure 7 , 8 As shown in Figure 11, in this embodiment, a fixing plate 260 is provided at the bottom of the T-shaped plate 240, and a limiting ball 261 is rotatably connected inside the fixing plate 260. The guide tube 250 is slidably connected to the limiting ball 261 inside the fixing plate 260, and the fixing plate 260 is located at the bottom of the positioning frame 161. The positioning mechanism 160 also includes several support frames 162, a two-way lead screw 163, several triangular blocks 165, several sliding seats 166, and several magnetic blocks 167. Several support frames 162 are fixedly connected to the bottom of the positioning frame 161. The fixing plate 260 is located inside the two support frames 162. The support frames 162 can support the fixing plate 260. The bidirectional screw 163 is rotatably connected to the positioning frame 161. The bidirectional screw 163 is rotatably connected to the inside of the operating table 110. Several triangular blocks 165 are slidably connected inside the positioning frame 161. The bidirectional screw 163 is screwed into several triangular blocks 165. Several sliding seats 166 are slidably arranged inside the positioning frame 161. Several magnet blocks 167 are respectively embedded in the bottom of several sliding seats 166. The top of the mounting rail 120 is provided with a second positioning mechanism 170. The first positioning mechanism 160 and the second positioning mechanism 170 have the same structure. The second positioning mechanism 170 is located on the top of the adjacent limit frame 150.

[0023] In practice, the fixing plate 260 can be inserted into the support frame 162. Then, the position of the fixing plate 260 can be adjusted according to the puncture requirements. The fixing plate 260 can drive the guide tube 250 to move through the limiting ball 261, so that the guide tube 250 slides within the limiting ball 261 and the limiting ball 241 rotates within the T-shaped plate 240, thereby adjusting the angle of the guide tube 250. The magnet 167 can attract the fixing plate 260, so that the fixing plate 260 is attached to the bottom of the positioning frame 161, thereby providing auxiliary positioning for the fixing plate 260. The fixing plate 260 can limit the angle of the guide tube 250 through the limiting ball 261, thereby providing auxiliary fixation for the puncture tool. The rotatable bidirectional lead screw 163 causes the two triangular blocks 165 to move towards each other. Under the action of the inclined surface of the triangular block 165, the sliding seat 166 can move upward, which can pull the second magnet 167 away from the fixed plate 260, reduce the attraction of the second magnet 167 on the fixed plate 260, and then move the operating table 110 away from the guide module 200, and move the operating table 110 away from the puncture site to facilitate observation of the puncture site. When puncture from the side is required, the positioning mechanism 2 170 and its bottom limiting frame 150 can be connected to an installation rail 120. Then, the sliding frame 230 can be slid along the U-shaped rod 220 to the side of the U-shaped rod 220. The T-shaped plate 240 is then placed against the positioning mechanism 2 170, and the fixing plate 260 is inserted into the support frame 162 of the positioning mechanism 2 170. In this way, the T-shaped plate 240 and the fixing plate 260 can be assisted in positioning by the magnet piece 164 and the magnet block 167 of the positioning mechanism 2 170, which makes the operation more flexible.

[0024] A slanted groove can be provided on the magnet piece 164, and a pull rod can be fixedly provided on the sliding seat 166. A round block that is slidably connected to the slanted groove is fixedly provided on the pull rod, and a round rod is fixedly provided inside the positioning frame 161 so that the round rod is slidably connected to the sliding seat 166. The moving direction of the sliding seat 166 is restricted by the round rod, so that the sliding seat 166 can only move up and down. In this way, when the bidirectional lead screw 163 is rotated in the opposite direction and the two triangular blocks 165 move in opposite directions, the round block can be squeezed through the slanted groove, so that the sliding seat 166 moves down to its original position. Alternatively, a through hole can be opened on the positioning frame 161 and a matching extrusion rod can be provided. The extrusion rod passes through the through hole and presses the sliding seat 166 down.

[0025] like Figure 3 As shown, in this embodiment, the control panel 110 is fixedly connected to the limit rod 111; The limiting mechanism 130 includes an arc-shaped plate 131, a rotating seat 132, a connecting seat 133, and a rotating shaft 134; The rotating seat 132 is fixedly connected to the arc plate 131. The connecting seat 133 can slide horizontally along the limiting rod 111. The connecting seat 133 is slidably disposed on the limiting rod 111. The rotating seat 132 is rotatably connected to the connecting seat 133. The rotating shaft 134 is fixedly connected to the connecting seat 133. The rotating shaft 134 is rotatably disposed inside the rotating seat 132. A damper is provided between the rotating seat 132 and the rotating shaft 134. The damper can prevent the rotating seat 132 from rotating arbitrarily relative to the rotating shaft 134. The angle between the rotating seat 132 and the arc plate 131 can be limited by the damper.

[0026] In practice, surgical instruments can be placed on the operating table 110. The arc plate 131 can be rotated as needed to adjust its angle. During the operation, the doctor can place his arm on the arc plate 131. Due to the damping, the arc plate 131 can be prevented from rotating freely. This allows the arc plate 131 to support the doctor's arm, which helps to reduce arm fatigue.

[0027] like Figure 9 and Figure 10 As shown, in this embodiment, a connecting ring 231 is rotatably connected inside the sliding frame 230 and slidably connected to the adjacent U-shaped rod 220. The connecting ring 231 can slide along the U-shaped rod 220. Since the connecting ring 231 is rotatably set on the U-shaped rod 220, it is convenient for the sliding frame 230 to pass through the corner of the U-shaped rod 220. The fixing seat 210 is fixedly connected to a U-shaped frame 211 that is slidably connected to the adjacent mounting rail 120. A clamping plate 212 is slidably connected inside the fixing seat 210. A connecting screw 213 that is rotatably connected to the clamping plate 212 is screwed into the fixing seat 210. The connecting screw 213 passes through the inside of the U-shaped frame 211 and abuts against the mounting rail 120. A rubber pad that abuts against the U-shaped rod 220 is provided on the side of the clamping plate 212. The clamping plate 212 uses the rubber pad to abut the two U-shaped rods 220 against the inside of the fixing seat 210.

[0028] In practice, when adjusting the position of the T-shaped plate 240 according to the puncture requirements, the U-shaped frame 211 can slide along the mounting rail 120, allowing the guide module 200 to slide along both mounting rails 120. The sliding frame 230 can also slide along the U-shaped rod 220, thereby adjusting the horizontal position of the T-shaped plate 240. Simultaneously, the U-shaped rod 220 can move up and down within the fixed base 210 to adjust the height of the T-shaped plate 240, ensuring it adheres to the operating table 110. After adjustment, it can be rotated. The connecting screw 213 can drive the clamping plate 212 to move towards the U-shaped rod 220, so that the end of the connecting screw 213 abuts against the mounting rail 120, limiting the position of the fixing seat 210. The clamping plate 212 can abut against the U-shaped rod 220 through the rubber pad, limiting the height of the U-shaped rod 220, thereby fixing the T-shaped plate 240. Under the attraction of the magnet 164, the sliding frame 230 can be prevented from moving horizontally along the U-shaped rod 220, thereby assisting in fixing the piercing instrument. When the operating table 110 is moved away from the guide module 200, the fixed base 210 can restrict the movement of the sliding frame 230 and the T-shaped plate 240 through the U-shaped rod 220, so that the T-shaped plate 240 can be smoothly separated from the operating table 110.

[0029] Example 2

[0030] Based on Example 1, such as Figure 5 As shown, in this embodiment, the support mechanism 140 includes a support column 141, a base 142, a support rod 143, and a fixing block 144; The base 142 is rotatably connected to the bottom of the support column 141. The base 142 is fixedly connected to the adjacent plug-in block 152. The support rod 143 is screwed into the inside of the support column 141. The fixing block 144 is rotatably connected to the top of the support rod 143. The fixing block 144 is fixedly connected to the operating table 110. The limiting frame 150 can support the plug-in block 152. The plug-in block 152 can support the base 142. The support column 141 can support the support rod 143. The support rod 143 can support the operating table 110 through the fixing block 144.

[0031] In practice, the support column 141 can be rotated as needed to move the support column 141 up or down along the support rod 143, thereby adjusting the overall length of the support mechanism 140 and thus adjusting the height of the operating table 110. Then, the limiting frame 150 and the base 142 can be rotated at the bottom of the support column 141 so that the limiting frame 150 corresponds to the mounting rail 120. The limiting frame 150 is then inserted into the mounting rail 120, thereby connecting the operating table 110 to the mounting rail 120. The support rod 143 can be set with graduations as needed to make it easy to adjust the four support mechanisms 140 to the same length.

[0032] like Figure 6As shown, in this embodiment, an abutment mechanism 180 is provided on the top of the mounting rail 120; The abutment mechanism 180 includes a fixed frame 181, an adjusting screw 182, a positioning rod 183, a positioning plate 184, and a pad 185; The adjusting screw 182 is rotatably connected inside the fixed frame 181, the positioning rod 183 is slidably connected inside the fixed frame 181, the adjusting screw 182 and the positioning rod 183 are screwed together, the positioning plate 184 is fixedly connected to the positioning rod 183, the pad 185 is fixedly connected to the bottom of the fixed frame 181, and the pad 185 is fixedly connected to the adjacent plug-in block 152.

[0033] In practice, the limiting frame 150 at the bottom of the abutment mechanism 180 can slide along the mounting rail 120, so that the positioning plate 184 corresponds to the patient's back or buttocks. The adjusting screw 182 can be rotated to make the positioning rod 183 slide along the inside of the fixed frame 181, so that the positioning rod 183 drives the positioning plate 184 to move closer to the patient and place the positioning plate 184 on the patient's body. When the patient is lying on his / her side, it is convenient to position the patient.
